Laser Blast

The object of Laser Blast is to destroy a series of land-based enemies. The player controls a fleet of flying saucers, operating one at a time.

On the planet surface below are a group of three mobile laser bases, guarded by an invisible force field that prevents the player's saucer from getting too close to the surface. Both the player and the enemy bases are armed with laser blasters, which may fire a single continuous beam at a time.
